Nevada Emissions Control Program

When to Test

Emissions Station Sign

Emission inspections are required for many original vehicle registrations and for each annual renewal. Your mailed renewal notice will indicate whether a test is required. Emissions inspections stations in Nevada are privately owned and decentralized.

You must have insurance and either a valid registration or a movement permit to operate a vehicle on public streets. If your registration is expired, you can obtain a movement permit by presenting the Certificate of Registration or other proof of ownership at a DMV office. You may be charged late fees and/or cited by law enforcement if you operate a vehicle with an expired registration.

Don't take your 1996 or newer vehicle in for an emission test right away if you have just disconnected the battery for any reason. Your vehicle will not pass the test and will be “Rejected”. The vehicle will need to be driven under varying conditions for up to one week in order for the On Board Diagnostics system to run all of its tests.

Vehicles Requiring a Test

Passenger cars, trucks, RVs and motor homes need an emissions test if they are:

Emissions tests are valid for 90 days.

You must have a valid Nevada test to complete any original registration or most renewals if the vehicle requires a test as listed above. This includes reinstatement of a suspended registration.

Nevada requires used car dealers to issue a valid emissions test, when required, on any vehicle they sell. In private transactions, the test is the buyer's responsibility.

Exempt Vehicles

The following vehicles are exempt from emission testing:

Test Fees

Test stations are privately owned and decentralized. The DMV sets the maximum testing fees each year. Stations are free to offer discounts, but they must post their charges along with an official DMV sign. Online Station Search/License Verification | Diesel Locations

Types of Tests

Nevada uses On-Board Diagnostics (OBDII) Testing for 1996 and newer vehicles. The operator will connect an analyzer to the OBD computer in your vehicle. Data from your vehicle will indicate whether its emissions systems are operating properly and within emissions limits.

Older vehicles are tested with a Two-Speed Idle Test.  The operator will test your vehicle once at idle speed, then test it again with the engine running at approximately 2500 rpm. Older diesel vehicles are tested on a dynamometer.

You Passed!

The test results are transmitted to the DMV immediately and you will receive a Vehicle Inspection Report. You may renew your vehicle registration at participating stations, on the Internet, at a kiosk, by mail or in person at a DMV office. See Renewal Options. There is no need to mail the report. First-time Nevada registrations and license plates can be obtained only at full-service DMV offices.

Test Failures & Waivers

Dashboard and Check Engine Light

If your vehicle has failed the initial emission test, you must repair it and pass a second test to be eligible for registration. If it still fails after repairs, you may be eligible for a waiver if you meet the requirements below.

If your registration is expired or about to expire, you may receive a temporary movement permit by presenting the failed emissions test at a DMV office. You may be charged late fees and/or cited by law enforcement if you operate a vehicle on public streets with an expired registration.

Repairs can be made by the owner or any facility the owner chooses. However, vehicles in Clark County must be repaired by a 2G Licensed Authorized Station to be eligible for a waiver. See our Online Business License Verification for a list of 2G stations in your area.

"No Pass-No Pay" options and similar promotions are not mandated by State law and are offered at the discretion of the individual station. Stations may charge for each test.

Waiver Requirements

If the vehicle still fails after being repaired, it may be eligible for a waiver. Your vehicle must fail:

Waivers will not be issued to:

Emission components could be covered under warranty for up to 8 yrs or 80,000 miles, whichever occurs first, under federal law. See EPA Emission Warranty Information.

Clark County

The vehicle must be repaired by a 2G Licensed Authorized Station to be eligible for a waiver. The waiver application must include receipts from the station showing that at least $450 has been spent on parts other than a catalytic converter, fuel inlet restrictor or air injection system, or on labor other than emission testing if the repairs evidenced by the receipt were directly related to the deficiency in emissions.

If the vehicle is not repaired at an authorized 2G station, it will not be eligible for a waiver, regardless of the cost incurred. See Business License Verification for a list of stations.

Washoe County

Waiver repairs may be made by a 2G Licensed Authorized Station or the owner. Vehicles repaired at a non-2G garage are not eligible for a waiver. See Business License Verification for a list of stations.

If the vehicle is repaired at a station, an application for a waiver must include receipts from the station showing that at least $200 has been spent on parts other than a catalytic converter, fuel inlet restrictor or air injection system, or on labor other than emission testing if the repairs evidenced by the receipt were directly related to the deficiency in emissions.

If the vehicle is repaired by the owner, the application must include receipts or other evidence that at least $200 has been spent on parts other than a catalytic converter, fuel inlet restrictor or air injection system purchased within 14 days after the initial emission test.

If you still fail after repairs - If you failed the initial test, did the repairs pursuant to your county's requirements, met the financial limit to obtain a waiver and your vehicle still fails for hydrocarbons/carbon monoxide or a Check Engine light, bring your vehicle, both failed certificates, and receipts for all repair work to the Department of Motor Vehicles Emission Test Facility to request a waiver.

Diesel

Waiver requirements for diesel vehicles are different. See the Diesel Emissions Requirements flier.

Smoking Vehicles

Smog Spotter Banner Ad

A vehicle which emits visible smoke will not pass an emissions inspection and does not qualify for any waiver. Law enforcement may issue citations for visible smoke.

The Nevada DMV also operates the Smog Spotter program to encourage the public to report smoking vehicles online or by telephone. Visit the Smog Spotter website or call one of the numbers below.

The DMV will investigate reports on any vehicle with a Nevada registration, including heavy-duty diesel trucks and vehicles based in rural areas.

Classic Vehicle Exemption

Vehicles registered with Classic Vehicle, Classic Rod or Old Timer license plates and driven 5,000 miles or less per year are exempt from emissions testing. Print-Friendly Fact Sheet (PDF)

Renewals

To renew the registration each year, you must complete the Restored Vehicle Odometer Certification for Emission Exemption (EC 18) to certify that you have driven the vehicle 5,000 miles or less. 

Mail this with your annual renewal or you may renew in person. Your registration renewal notice will list "Smog Check Required" each year. You will not be able to use alternate renewals. You must renew in person or by mail. If you drive the vehicle more than 5,000 miles in one year, you must obtain an emissions inspection if your vehicle and region require it.

Initial Issuance

If you have received a failing emissions test within the last 90 days, you will not be able to obtain the license plates for the emissions exemption.

To obtain the plates and exemption, the vehicle must meet the requirements listed on one of the following applications:

See also Classic Vehicle License Plates. Download and complete the appropriate application.

You must also complete a Restored Vehicle Odometer Certification for Emission Exemption (EC 18).

There are several fees for the initial purchase:

Bring the completed application, the EC 18, any existing license plates and your Nevada Evidence of Insurance card to a DMV office. If you wish to keep the old plates, you must bring the rear plate and surrender the decal in person.

We will issue your new plates with a new registration slip and decal. No registration renewal is required and your expiration date will remain the same.

You have the option of renewing your vehicle registration for a full year. Your expiration date will change if the current expiration date is more than 35 days away. Credit will be given for the unused portion of your current Nevada registration.

If your vehicle is not currently registered in Nevada, you must meet all other registration requirements.
